The tree menus follow the reference per row kind (New Sheet / Import on a sheet work on its subset, Remove Subset only while empty, Rename Subset), a new sheet is not opened, an open set reloads when its .dst changes on disk, ViewportScale placeholders take the version of their format and the codec pin moves to the revision with navigation fields.
